Many workers perform their daily activities outdoors and many anatomical body sites are exposed to UV radiation. The effects of solar radiation on human health depend on the amount and type of radiation impinging on the body. This paper aims to investigate and analyse the diurnal UV radiation exposure at typical anatomical site for farm workers. The diurnal distribution in solar UV exposure at ...

BACKGROUND Hispanic immigrant workers dominate California's hired farm workforce. Little is known about their health status; even less is known about those lacking employment authorization. METHODS The California Agricultural Workers Health Survey (CAWHS) was a statewide cross-sectional household survey conducted in 1999. Six hundred fifty-four workers completed in-person interviews, comprehe...

This paper contributes to the assessment of China’s rural labor markets, while paying attention to whether these markets are developing in a manner conducive to the nation’s modernization. According to our household survey, we find that the rapid increase in off-farm employment has continued and accelerated during the late 1990s. Our analysis shows that migration has become the most prevalent o...

IRELAND was once thought to be free of Q fever (Kaplan and Bertagna, 1955). An investigation of patients, abattoir workers, veterinary surgeons, farm workers and farm animals in Northern Ireland showed that Q fever was present and entered the country sometime between April 1957 and February 1962 when the first known clinical case occurred (Connolly, 1968). In the Republic of Ireland a survey wa...

In Year 1, there are only ten factories, which can employ a maximum of 100 workers. Hence most farms will still have all five siblings working there. The total farm income will be $100, so the average product of labor is $20 = 100 5 . The marginal product is 0, since when there are at least three siblings working on the farm, any additional worker does not increase farm income. Consequently two...

Background: Q fever is a zoonotic disease caused by Coxiella burnetii. In Colombia it is not a notifiable disease in humans and is most likely under diagnosed. There are no studies about its prevalence in important reservoir species, such as cattle. Objective: the aim of this study was to investigate the frequency of C . burnetii infection in cattle farms and determine the frequency of antibodi...

This study aimed to investigate the relations among mental disorders, physical discomfort, household work and farm work among women. We conducted a cross-sectional study based on the administration of a structured questionnaire to 182 female farm workers. The data were analyzed by means of Poisson regression, where the significance level was set to 5%. Results indicated that 111 (61%) participa...

Previous studies have indicated that farm workers may be at increased risk of gastric cancer. Meta-analyses, ecological, case-control, and cohort studies suggest that some aspects of the agricultural environment may be implicated in the elevated risk. Hispanic farm workers in California are exposed to a multitude of potentially toxic substances in the work site, including excessive sunlight, fe...

Rotator cuff disease, among others damage of the supraspinatus tendon mainly caused by work overload, is a common problem in the population resulting in a high incidence of sick leaves. In the present survey we sought to compare the need for sick leaves in relation to different stages of supraspinatus tendon affection and in relation to five different groups of workers. Our study counted with t...
